Powerflush London

quality powerflush by specialist company

modern equipment + high performance chemicals + knowledge = excellent powerflush results.

We use latest technologies to perform powerflush efficiently and thoroughly. We’ve always believed that successful powerflushing is derived from moving water as fast as possible through a heating system to mobilise and transport the debris to a point where it can be forcibly discharged.

Thats why we use Kamco Clearflow CF90 Quantum powerflush pump which can deliver 150l/min flow. The all important flow rate is achieved without increasing maximum pressure beyond 1.8 bar, to ensure that no damage will be done to a heating system. The flow rate is more than double that of most power flushing pumps on the market, enabling it to remove more debris from a system and in less time.

Power flush should be done by a central heating professional, someone who works on gas boilers and central heating systems all the time, therefore "Gas Safe registered", it will be much better than one who just accomplished 3 hours powerflush course.

We are proud to be Gas Safe registered (our number is 515253) confirming that Powerflushdoctor engineers are heating professionals.

We have been trained to powerflush Worcester-Bosch boilers.
